Note:

1. Quantities based on data gathered at ONS for years 1977 and 1978, and values found in Evaluation of compliance with 10CFR50 Appendix I, June 4, 1976. Actual amounts vary from year to year depending on unit operating history. The actual liquid waste generated is reported in the Oconee Annual Effluent Report. The actual gaseous waste activity that is released is reported in the Oconee Annual Effluent Release Report.
